- and more particularly to shingles of the character which are fabricated from sheet material of a fibrous nature, treated with bitumi- I nous material to impart weather resistant qualities'thereto; and to render them" flexible and non-porous and the shingle and especially the lockin means provided thereon forming the sub ect matter ofmy invention is L an improvement over other shingles in that it permits notonly one but several arrangements of the shin les with relation to each other and thus give the purchaser of the shingles'his choice in the arrangement of the IE shingles while the manufacturer need only make practically one type of shingles to-' gether with suitable types of starter shingles and possibly different. sizes of shingles. Another objectof the invention is to pro vide such a shingle with novel means for eflicientlylocking a plurality of them to one another and hold the butt ofv'each shingle stiff and straight.

' Another object of the invention is to provide a locking member for the shingles which will prevent the butt of the shingle from being-lifted by wind or warping.

- These and other objects of this invention will be" apparent from the drawings, the

ing a part thereof.

In the several Kfigures of the drawings like reference numerals indicate like parts.

. As illustrated in Figures 1 and 2 each in-. dividual shingle or unit indicated by reference numeral 3 consists of a rectangular sec tion or sheet of water proof and weather prooffibrous material which may be either ofuni-' form thickness or which may be heavier at one side as will hereinafter be described. At the bottom each of the shingles has a flange 4 bent upwardly at the back thereof to provide' a flap at the back of each shingle. "At t-he lower right handend each shingle is cut awa as indicated at 5 and the flap formed at t e back of each shingle extends from the left hand side of the shingle to this cut away portion at the right hand side thereof. The corners of the flange 4 which forms the flap are angularly cut away at each end thereof.

' 'Fastened into the fold of the flap of each i of the shingles is the metal locking strip 6.

' This strip is riveted to the flange 4 as illus-I trated at 7 and 8 in Figure 2 and projects about an inch from the left hand side of the shingle near the lower corner 'thereof.

In Figure 3 I have illustrated how the sep-.- arate shingles or units 3 are interlocked with one another as a'course of them is laid in covering a roof. The shingles are properly lined up with each other and each of them is nailed to theroof with suitable nails which in line with the shingle already fastened to the roof in such a. manner that the overlapping lower end of the new shingle will engage into the cut away portion of the anchored shingle and thus bring the lower edge of the new shingle in perfect alignment with the anchored shingle. This is illustrated in Figure 3. Each shingle thus has its left hand end overlap the right hand end of the preceding shingle a distance equal to the length of the cut away portion provided at the lower right hand corner of each of the shingles while the locking strip 6 thereof engages the narrow channel of the preceding shingle which has been fastened to the roof and thus locks the lower corner of the lefhhand side to the preceding shingle. The right hand end of each shingle as well as the upper end thereof is then nailed to the roof in any suitable manner except that the nail driven into the position indicated by reference numeral 9 in Figure 3 must be located as pointed out above in order to permit the next shingle to be locked to the shingle in process of being fastened to the roof. The nails for fastening the right hand side andtop of the shingle are of course locatedso that as other courses of shingles are laid, their lower edge will overlap and cover the heads of the nails so that they will not be exposed to the weather. g

In Figures 7 to 10 inclusive I have illustrated some of the various arrangements in which the shingles may be laid to cover a roof. The arrangement illustrated in Figure 7 provides a singlelayer roof in which the sides of the shingles are in line with each other. The arrangement illustrated in Figure '8 illustrates a single thickness roof in which the shingles are staggered with relation to one another. Figure 9 illustrates a triple thickness roof in which three courses of shingles overlap one another. vA double thickness (not shown) is similarly arranged.

The arrangement illustrated in Figure 10 shows the shingles laid in angular courses. In this arrangement a starter shingle 12 is needed to start off each course at the edge of the roof with a straight instead of an angular bottom. This is illustrated in Figures and- 10. The starter shingle used for this purpose is illustrated in perspective in Figure 6 and I has a flap formed bythe flange 13 at the back thereof. The left hand end of this starter shingle is cut away at 14 similar to the cut away portion 5 of the shingle 3 and the right hand end of the starter shingle is cut away pared in this way looking at it from the rear.

The bent up portion of this shingle can thus engage under the edge and side of the starter shingle and thus lock this shingle to the starter shingle. The remainder of the shingles are laidandflocked together in the same way as described in connection with Figures 1 to 3 inclusive except that each course of shingles extends at an angle to the edge of the roof instead of being parallel thereto.

The fact that a flange is provided at the bottom which is bent back makes the bottom of the shingle thicker than the sides. For this reason one side or the top of each single may be made thicker along the edge in order to make it look as thick as the bottom or nearly so. This is especially desirable when the shingles are laid only in the angular arrangement as it will make both of the exposed edges appear the same in thickness and not one heavier than the other.

I claim: 1. Aflexible shingle having a flange bent up at the back to form a rear flap along one edge thereof, a locking strip anchored in the fold of said flap and projecting from one end of said shingle, the other end of said shingle being cut away to permit the engagement of the flap of the succeeding shingle under a portion of the first named shingle with the bottom edges of bothshinglesin line witheach other, said locking strip being adapted to engage into the fold of the flap of the preceding shingle to hold the shingle locked hereto.

2. A flexible shingle having a flange bent under to form a flap along one edge'thereof, a fastening member comprising a narrow metal strip anchored in the fold of said flap and forming a continuation of said flap of reduced width and projecting from one end of said shingle to engage under a portion of the end of the preceding shingle with the fastening member of the succeeding shingle engaging into the fold of the flap of'said preceding shingle. Y

3. A flexible shingle having one edge thereof cut away a predetermined distance at one end thereof, a flange bent under to form a flap in'back of said shingle beginning at the cut away edge thereof, and a locking strip anchored in the fold of said flap and pro- 7 CHARLES L. MANGANO.
